NAME
Apache::Stage - Manage A Staging Directory
SYNOPSIS
# this location is served by normal apache. It's recommended to
# restrict access to this location to registered authors of this
# site, but a restriction isn't necessary
ErrorDocument 403 /stage-redir
ErrorDocument 404 /stage-redir
# the name of this location must match the ErrorDocument redirects
# above
# PerlSetVar apache_stage_regex " ^ (/STAGE/[^/]*) (.*) $ "
# This regex has to split a staged URI into two parts. It is
# evaluated with the /ox switch in effect, so this will NOT be a
# per-directory variable. The first part will be thrown away and
# just the second part will be served if the original URI cannot
# be accessed. In case of 301 and 302 redirects the first part
# will be prepended again. The default regex is defined as above
# which means that URIS will be split into "/STAGE/anyuser" and
# the rest.

DESCRIPTION
A staging place is a place where an author of an HTML document checks
the look and feel of a document before it's uploaded to the final
location. A staging place doesn't need to be a separate server, nor need
it be a mirror of the "real" tree, and not even a tree of symbolic
links. A sparse directory tree that holds nothing but the staged files
will do.
Apache::Stage implements a staging directory that needs a minimum of
space. Per default the path for the per-user staging directory is
hardcoded as
/STAGE/any-user-name
The code cares for proper internal and external redirects for any
documents that are not in the stage directory tree. This means that all
graphics are displayed as they will be later after the staged files will
have been published. The following table describes what has been tested:
Location Redirect to Comment
/STAGE/u1/ / Homepage. Internal Redirect.
/STAGE/u2/dir1 /dir1/ Really /dir1/index.html
/STAGE/u3/dir2 /dir2/ Directory has no index.html
Options Indexes is off, thus
"Forbidden"
/STAGE/u4/dir2/foo /dir2/foo Internal redirect.
/STAGE/u5/bar - Exists really, no redirect
necessary
/STAGE/u6 - Fails unless location exists
The entries described in SYNOPSIS in the access.conf or an equivalent
place define the name of the staging directory, the name of an internal
location that catches the exception when a document is not in the
staging directory, and the regular expression that transforms the
staging URI into the corresponding public URI.
With this setup only ErrorDocument 403 and 404 will be served by
Apache::Stage. If you need coexistence with different ErrorDocument
handlers, you will either have to disable them for /STAGE or integrate
the code of Apache::Stage into an if/else branch based on the path.
